I To a/ZZ whom it may oon/cern.:

Be it known that I, MAURICE BRIET, a'citizen of the French Republic, residing at 57 Rue Damrmont,in the city of Paris, France,

haveinvented certain new and useful I'mprovements vin Mechanical Lubricators wlth Archimed'ea'n Screw and Pressure-Controller,

of which thev following is a full, clear, and eX- act specication.

The present Invention relates to a' mechanical lubricator with Archimedean screw which is adaptedv to lubricate all the parts of a driving-machine or other apparatus to be oiled under pressure, as well as without pressure.

A lubricator of this class is illustrated in ythe'annexed drawings, in which- Figure 1 is a vertical sectionalong line 1 1,.

Figs. 3 and 4; Fig. 2 a sectional detail view; Fig. 3, a front elevation, and Fig.y 4 a' lan view showing apart with the oil-channe s 1n section.

erably by a pu ey a, a gear-wheel, or the like keyed on the outerend of a solid cylindrical' shaft b with an enlarged head or collar at the 1 other end, said shaft having an Archimedean screw c between the ends, which may be worked out of the metal of the shaft or which can be madeseparately and then be inserted and secured between ,the two cylindrical pieces forming the ends of the shaft. `Thel said shaft passes through an ordinary stuing-box d e into a cylindrical bore or space in a casting integral with an oil-receptacle r. The part of the casting with said bore or cylinder is situated in the middle ofthe oil-tank slightly above its bottom. The bore communicates with the' bottom of the oil-tank through a port ZL, as shown in Fig. 1. The foot end of the shaft turns in a suitable bearing f, inserted in the bore for the Archimedean screw. The bearing f may be provided with ball race or groove adapted to receive balls g, so that a smooth frictionis produced. Then the head at the foot end of the shaft b is pressed against it, reducin the wear and tear of the shaft. The shaft b 1s inserted through Va suitable opening, which is .then closed tightly by a screw-plug w, whereupon the stuffing-box (Z is tightened and the pulley o is secured* on` the outward -projecting end of shaft b.' The oil is carried along by threads of the screw c'toward one end of the sur-` rounding space when the shaft b revolves and 1s pressed 1nto a tube i, ascending through the reservoir 1' andcarrying at its upper part a suport j, supporting a number of dropnozz es m. These nozzles are secured in vertical openings having female threadl '0, and a longitudinal channel 7c, extending from one end tothe other in the support, Figs. 3 and 4, l connects said screw-openings, and a crosschannel Z at thesame Aheigh't as channel 7c connects these openings with the upper part.

of ythe tube fi. ach drop-nozzle m has an 'annular groove n, Figs. 1, 2, and 3, and a transverse channel o, which can be closed.- more or less byl a needle-valve o of ordlnary construction. When the point of said valve is screwed home, theoil in the channel o cannot pass downward into the vertical bore to feed the parts to be oiled; but thel communication from the pipe Z through channel Z, the` annular grooves n, and channel Zc remains open, so that all nozzles are supplied with oil',

and only those having the channelfo o en"` more or less by the needle-valves allow oi to Motion is im arted to the mechanism prefdrop down for lubricating.

A pressure-contrfller p is arranged in the upper art of the apparatus, so that as soon as the ubricator is operating the air and the excess of oil escape and return tothe recepf tacle r through .the overflow-pipe g.

To char e the apparatus, a' stopper .s is removed. glass tube t is used to show the contents of the reservoirr. 'u is a glass tube inserted between the lower end of each no'zzle and the upper end of a supply-pipe y which leads the oil to the parts to be lubricated. e

Figs. 1 and 2 illustrate how the glass tube the lower part of the body recedes in the threading o far enough to close up the chan- The nut holding the glass, is unscrewed at and thereafter the parts are screwed up again in such a manner that the glass tube is nel Z and Z, the longitudinal channel 7c, Fig. 2.

thesame time, and the glass when brokenl can be removed to be replaced by a new one,

jammedin, and the nut x is screwed in place,

as illustrated in Fig. 1.

The apparatus operates in the following manner:y The screw c presses the oil of the reservoir r upwardly in the stand-pipe i, as

described, and the channels Z and 7c convey it to all the nozzles m, keeping the cross-channels o Jlled; Any of the needle-valves may be opened more or less, and the oil will drop from their'channels 0 vertically down into the pipes ly, and the flow can be readily ex-l amined through the glass tubes a, so that the operator may regulate the flow according to necessity by screwing the needle-valve o more or less against its seat.

A plug z is provided under the apparatus for cleaning the same.

Having thus described my invention, what I- claim as new is- 1. In a mechanical lubricator an oil-reservoir7 a cylinder near the bottom ofthe same, and in communication therewith an Archimedean screw revolubly journaled in said cylinder and driven by the machine, a stand.- pipe L and a support y' carried thereby at its upper end, a delivery-nozzle screwed into said support y', a needle-valve adapted to open and close said nozzle, an oil-pipe y leading to the parts to be lubricated and a glass tube u inserted between said nozzle and said oil-pipe, substantially as described.

2. In a mechanical lubricator an oil-reservoir, a cylinder near the bottom ofthe same, and in communication therewith, an Archimedean screw revolubly j ournaled in said cylinder and driven by the machine, a standpipe i and a support carried thereby at its upper end, a pressure-valve p in said support above the stand-pipe i and an overflow-pipe g for the excess of oil, a deliverynozzle screwed into said sup ort y', a needle-valve adapted to open and c ose said nozzle an oilpipe y leading to the parts to be lubricated and a glass tube u inserted between said nozzle and said oil-pipe substantially as described.

3. In a mechanical lubricator an oil-reservoir, a cylinder near the bottom of the same, and in communication therewith, an Archimedean screw revolubly journaled in said cylinder and driven by the machine, a standpipe i and a support j carried thereby at its upper end, a number of delivery-nozzles, screwed into vertical openings of the support and comprising annular grooves n, said support having longitudinal channels 7c between the individual nozzles in communication with the stand-pipe c' by said annular grooves and a channel l, needle-valves adapted to open and close said nozzles, oil-pipes y leading to the parts to be lubricated and glass tubes u inserted between said nozzles and said oilpires substantially as described.

n witness whereof I have hereunto set my hand in presence of two witnesses.
